Abstract:
A principal component of our construction for dual-server public key file encryption with keyword search is smooth projective hash function, an idea created by Cramer and Shoup. During this paper, we must have decision concerning property of smooth projective hash functions. We introduce two games, namely semantic-security against selected keyword attack plus distinguish ability against keyword guessing attack1 to capture the safety of PEKS ciphers text and trapdoor, correspondingly. No matter being free of secret key distribution, PEKS schemes get an natural insecurity in regards to the trapdoor keyword privacy, namely inside Keyword Guessing Attack. Regrettably, it's been determined the traditional PEKS framework is battling by permitting a fantastic-natural insecurity known as inside keyword guessing attack launched while using the malicious server. Additional security vulnerability, we advise an entirely new PEKS framework named dual-server PEKS. You have to show a normal construction of secure DS-PEKS from LH-SPHF. Our plan's considered because the efficient in relation to PEKS computation. Because our plan doesn't include pairing computation. Particularly, the present plan necessitates most computation cost because of 2 pairing computation per PEKS generation.
